CARPET-STRETCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 370,257, datedSeptember 20, 1887.

Application filed December 4, 1886. Serial No. 220,669.

To aZZ whom it may concern:

Be it known that I, LEONARD HINKLE, a citizen of the United States,residing at Kenton, county of Hardin, and State of Ohio, have invented anew and useful Carpet-Stretching Machine, of which the following is aspecification.

Myinvention is an improved carpet-stretcher, and seeks to provide animplement by which the carpet may be stretched by a person standingerect, and the use of which will not result, when properly operated, inany danger to the carpet.

The invention consists in certain particulars of construction and novelcombinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a plan view of the stretcher. Fig. 2 is aside view, partly in section. Figs. 3 and 4 are detail sectional viewsillustrating the pawl-box, and Fig. 5 shows a different arrangement ofsome of the parts from that shown in Figs. 3 and 4.

The draw-bar A is provided at one end with means by which it may besecured to the floor, the same being preferably dogs H, as shown. Thisbar A is provided on its under side with rack-teeth B, and similar teethare preferably provided on its upper side also. Along the sides of thedraw-bar are formed ribs A, as shown, extended longitudinally andserving to strengthen the bar, as will be apparent.

The stretching head has an opening, I, formed to receive the draw-bar,as shown in Fig. 5, and to permit the head to be moved along said bar.The lower wall of the opening 1?, at P, forms a pawl or bearing, whichengages the ratchetteeth on the under side of the draw-bar. Immediatelybelow this pawledge P the head has a recess or indentation, K,whichreceives the teeth B in the operation of the invention and prevents thehead from presenting an inclined bearing to the said teeth B. The headmay be extended upward to form a handle, or may be socketed, as shown atM, to receive a separate handle or staff, F, as may be desired.

At its lower end the head is provided. with a grapple-bar, G, havingsuitable teeth for engaging the carpet. These teeth are preferably ofthe tapered form shown, because thereby (No model.)

they will not be likely to injure the carpet. The bar G has a rib, J,which serves to prevent its bending or breaking. To this bar G ispivotally connected at E the ends of the pawl-bail D. The centralportion of this bail may be arranged to engage the teeth of thedraw-bar, as shown in Figs. 1 and 2, thus forming a detent; or the bailmay be constructed with a box, J, which has opening N and slides 011 thedraw-bar. The pawl I is pivoted at its rear end on pin 0 and engages therack, as shown. Manifestly either of these detent constructions can beused.

In operation the dogs H are placed close to the wall and the head ismoved out to the opposite end of the draw-bar. Then by pressing thegrapple-bar to the carpet and operating the lever the carpet will beproperly stretched, and great force may be exerted to such end.

The invention is simple and will be readily understood. It is obviousthat by arranging the pawl below the bar A and causing it to engage theunder teeth of said bar the upper rack-teeth might be omitted.

A special advantage results from the particular form of teeth providedon the grapple bar. These teeth are beveled on each side or edge and atthe back, and properly engage the carpet without coming in contact withthe floor, whereas the ordinary stretchers have spike-like teeth,whichpass through the carpet and enter the floor, being thereby frequentlybent and broken.

I claim-- 1. A carpet-stretcher comprising a toothed draw-bar, a headhaving an opening fitted over said bar and having the lower wall of saidopening formed with a pawl-like edge to engage the lower teeth of thedraw-bar, and the detent pivotally connected with said head,substantially as set forth.

2. The combination, with the toothed drawbar, of the head having anopening formed to fit over the draw-bar and having the lower wall ofsaid opening formed with an edge arranged to engage the lower teeth ofthe drawbar, and the detent-bail having its ends pivotally connectedwith the head on opposite sides of and below the drawbar, substantiallyas set forth.

3. The combination of the toothed drawbar,

the head having an opening fitted thereover, and having a grapple-barand a pawl or bearing to engage the draw-bar, and the box J, connectedwith the head and having pawl I, all substantially as set forth.

4. The improved carpet-stretcher herein described, consisting of thetoothed draw-bar, the head having an opening, '1, and a bar, G, andhaving a pawl or bearing, P, and a recess or indentation, K, below saidpawl P and the detent, substantially as set forth.

5. The improved carpet-stretcher herein described, consisting of thetoothed draw-bar having dogs Hand provided with the longitudinal sideribs, A A, the headhaving an opening, 1?, and provided below the samewith a pawl-like edge, P, arranged to engage the lower teeth, B, and thebox J, sliding'on the draw-bar and connected by bail-arms D with thehead and'the pawl in said box, substan- 2o tially as set forth.

LEONARD HINKLE.
